All but the highest end EVs will likely switch to a LiFePO4 battery chemistry, this chemistry is much more stable under destructive conditions and are less prone to combustion and thermal runaway.
And the only penalty is about a 10% energy density loss. The chemistry also charges / discharges on a very flat curve, which means it's not sufficient to monitor voltage levels and temperature to know the current charge state, you have to also monitor power-in / out and time and make a best guess, which requires semi regular calibration.
The upside is that you can always charge to 100% and it has almost triple (I think) duty cycles compared to traditional liOn
